A second hollow nipple 56 is threaded imo the wall 12 and is in open communication with a port 57 which connects the hollow ni ple with the interior of the chamber.

Tlie device shown -in Figs. 'l toj4 inclusive is' adapted to be einfpliy'edfwith `a .machine which 'hasa forced ee lubricant supply so that the inlet of the force feed is attached to the threaded nipple 54, while the outletis attached to the threaded nipple 56 for maintaining a constant supply of 'lubricant tothe y internal chamber 11..

-Eth one of the`v cylinders 20 is provided 58 for placing the chamber 11 -in communication with the cylinders above the lunger 23,and the sleeve 24.

e' operation of the device shown in Figs.

1 yto 4 inclusive, is as follows:

lAfterthe Anipples 54 and 55 have been connected to the'p) er leads of an inlet and exhaust of alu cant suppl the device is ready foroperation. It will necessary to depress the treadle 46, thereby actuating the lever 41 against the spring 42, whenebjy'` the shaft 40 will be rotate lie ratchet 5U Aof the spring, the cylinder forcin the lubricant ini-'Uil periodically and successively actuate' the plungers 23 s that ally of the plungers4 will e brought into action' for forcing the lubricant from the various cylinders through the nipples to the various parts to be lubricated.

Figures 5 to 7 inclusive, disclose'a form of i container forstoring lubricant and for forcing' the lubricant under pressure, to the de-y vice shown in Figs. 1 to'4 inclusive. The

storage container includes a c linder 60 having a tapering discharge en 61y and a ca 62 threadedonto the `upper end of the cyl inder. The reduced portion of the tapered end 61 is provided with avthreaded nipple 63 which is ada ted to be connected by means i.

of a flexible ose to the nipple 54 which isf.`

in communication with lthe inlet port 55. In this'case the threaded nipple 56 is removed, and a plug is substituted which will close the discharge port 57. The gland 65 is threaded into a passage in the tapered portion 61. A; valve cage 64 is carried by the gland to permit the filling of the container by the usual hose connection at a filling 'station when applied to the valve cage.

A and lias a .packing 67 secured to the outer face with a ldisk 68 adapted to sup ort the packing. A bolt 69 connects the dis 68 and packing 67 to the piston y66. A spring 70 iston 66 is mounted in the cylinder 60 has onevend in engagement with the iston 66,' and its other end engaginga shoul cr 71 formed onthe cap o r closure 62.

The shaft 72 is rotatably mounted in the reduced portion 73 of the cap 6,2, andv has one end'internall threaded Ato' receive the threaded end 74 o astub shaft 75 rigid with a wall 76. A cable 77 has one end secured to a nut -78 which is threaded onto the `bolt 69. Theother end of the rope is secured to the shaft. 72 and coiled on the same.

A ratchet 79is secured to the shaft 72 and a paivl 80 pivoted at 81 is adapted to enga re the teeth of the ratchet 79 `and maintain t 1c shaft againstrotation;

The operation of the" device shown in Figs. 5 to 7 inclusive, is as follows:

When it is desired to fillthe cylinder 60 the usual connection of a hose is placed in engagement with the valve cage 64. Since the lubricant at a filling station'is usually under pressure, lubricant will fill thetapered portion 6l of the cylinder, and force v the piston 66 upwardly aginst the tension ing filled as the wiener.-

'st n riore/cl outwardly. `When the cylinder hes been filled, the pewl 8O is moved engr; ient with the 'teeth of the t T9., thereby preventing the spring 70 ,from tending to niove the piston in the pnosite ldirection and thus relieving pressure on the lubricant in the container. lr'hen this container is attached to the distributor shown in lfiscgs. 1 to i, inclusive, the, puwl 8l) is released lor permittingl the spring; to eet upon the liquid in Suid contuiner und exercise ai in'edetcrinined pressure on the saine. thereoy forcing the lubri xunt through the nipple 63,-through the hose connection, not shown, und into the chamber 11 of the casing i@ of the distributor shown in Fig. l. lll/Then the treudle i6 is depressed the shaft Ll() vvill be revolved, causing rotution ot' the cani member 47 and thereby successively operating the various plungers.

Figures und 10 disclose combined unit of e storage container and a distributing' unit. A cylinder is tl re-ided at its open end onto e block 8S in which the distributing unit is mounted and closes the lower end of the cylinder. The' opposite end et the cylinder is closed, es sluinvn. :it 87, :ind e, threaded opening in which mounted e. gland. 8S which seals the upper end of the hollow shutt 89, the shaft being located eX- iullj' of the cylinder The leisten ll() is slidably mounted in the in and has u boss 91 exnbriicingr the hollow i 4 piston in proper alineinent when Suid piston slides on the shaft A spring 92 has one in'engugenient with the piston 9G and the other end enfluging i shoulder 93 formed on the inner Well of the cylinder 85 for maintaining the piston et the bottoni the cylinder.

The plunger 10G is threaded into the sleeve in thc seine menne-r as has been vpreviously described, and is illustrated more particularly in Fig. 3 of the drawings, so that the length of the stroke of the plunger muy be varied for controlling the supply of lubricant to a moving part'. A nipple 167 islthreaded into the outer end of each cylinder to which is adapted to be connected a 'liexible hose which connects n cylinder with u nipple oil bearing or other part which. it is adapted to lubricate.

A cam 108 is'secured t-o the shaft 89 and is provided with it resilient pewl 109 adapted to engage the teeth of the ratchet 110, so that when the shaft is revolved the ratchet and likewise the cem member will be revolved for causing the eem member to move the plungers 106 outwardly for forou ing; lubricant from the cylinders. A lever 111 is secured. to the outer end of the hollen shaft ,89 andv is ade ted when rocked, to

rock the shaft 89 wiereby the cam member 108 operates the lungers.

Lubricant is supp led to the `port 95 in any approved manner und under pressureso that us the lubricant is dicharged. through the ports 98, vthe pieton 90 will he moved to the opposite end ot the cylinder against 'the j action of the springr 952. After the cylinder has been filled, the device is now ready for operation, and the lubricant in said-cylinder is under pressure so that when tlie lever 111 is rocked it will oper-utc the plung`l ers 4106 and cause the lfluid to be successively forced to the various parts to be'1ubricated.-f

Referring' more particularly to Figs. 12am 15 inclusive, it will be seen that a distributor und=storage container are combined as' u single unit, und present a modified form of i the construction shown in igs. 9 and 10. ln this instance, the construction of the disl tributor is similar to that Shown in Figs; l to i. inclusive, and consists of e casing' 120 having nu internal chamber 121 in which are located n plurulity'of radially disposed cylinders piston 123 is slidably mounted in euch eylinder and is forced radially inwardly by ineens or a spring 124. A valve cage 125 is screwed into the outer end of each cylinder and carries a spring pressed The outer end of the cage is threaded et 12T to provide a nipple for connecting the seine by means of e hose to the nipple of a bearing,

A shaft 128. is mounted uxiellyof the eas- `ingl20 to which is secured e, rlitchet 1329 .adzfpted toengage ir pewl '13() securedto, u enm'nie'niber 131` which when revolved. forces the plungersl'123 outwardly. 'port 132 bluees the; internal chamber 121`i'n communicitticn with n, cylinder-122. -A lever 1855 is secured tothe outer )rejecting end of a shaft 128 and isadnpte.` to he oseillated for -rocking'theshaft 128 and operating succesnio sivelyA the plungers 123. A spring 134 is secured. to the casing 12C` and is adapted to engage the lever 133 for resisting operative movement of the lever. `The spring 134 is adjustable so that its tension may be varied according to the resistance desired. against the movement of the arm-133.

A storage container 140 has a tapered portion 141 which is connected by means of a hollow stem 142 to the outer end of the lever 133. The stem has a passage 148 which is in open communication with theiassa e 144 in the lever 133 forv a purpose whic will be presentl explained. y i

The sha t 128 has a passage 145 whichplaces the passage 144- 'in communication with the chamber 121.v The pistonx 146 is;

of the cylinder 140. The va ve rests nor mally upon a disk 155 which is threaded into the memberl154. A stein 152 is reduced 'and threaded intothe valve 153 for said valveto 'the stein whereby rotation-o said threaded portion 156 passes through the stem will cause rotation of the vulve. The

155 and is, provided a head 157 enga ed by a 'spring 158, which'maintains the va ve 153 in snug'engagement with the disk 155:

The valve is provided with a port 159 ada ted to be alined .with a port 160, where y' lubricant from the cylinder 140 will passM through the orts and into the passage 143."

'A flexible h 162 `of the casin 120 with "the passage 143.(

v .A gland 165 is t rea-ded into an opening in ".theltapered portion 141,and a valve cage V164 is carried by the gland. 'This cage pro- 'vides means `forv applying the usual hose,

` connection of a lubricant supply under pres- 'fflll gat a filling station so that the lubricant may beforced into the container, under pres- -sii,i'e, and move the piston 146 to the outer end or the cylinder. The valve (not shown) in the cage-presents lubricant vfrom being v discharged from cylinder 14:0.l Valve cage 164 is similar to the valve 'cages '64 and 94.

The operation of my device is as :tollows: When the cylinder 140i is filled with lubricant, the treadle 150 is depressed. forcing the piston 146 inwardly and causing lubricant, under pressure, to flow tothe chamber 121, through the tubell. As the treadle is depressed the cylinder 140 `isinoved in-A wardly causing lactuation of the lever 133 which engages the spring 134, slightly be in the casi diskl ose 161 connects an inlet port comprising a casing,

fore said lever contacts with the stop 170.

The shat.128 is thus revolved, causing the cam member 131 to actuate the plunger 12,3 which successively forced lubricant from their respective cylinders to the parts of the machine adapted to bel lubricated. Lubricant is forced into the distributor 121 fromtlic cylinder 140 by the piston 146 aboutthe time that lever 133 engages thc spring '134.

A stop^170 is provided which will be cn- 75 gaged by the lever '133 to limit the movement' of said lever.v A coil spring 42 is C011-,r nected between the lever 133 land a side wall ofthe casing 120 -for aiding in returning the parts to their normal inoperative position.
